Chiroptera is the second largest mammalian group after rodents, bats possessing unique physiological adaptations with relevance to their disease susceptibility and reservoir competence. In this project we aim to describe and understand the factors influencing intra- and interspecies variability in bat’s immunity.

Chiroptera is the second largest mammalian group after rodents. Bats have unique physiological adaptations, provide important ecosystem services, but are threatened by various anthropogenic activities. They are highly mobile and social, host a diversity of zoonotic pathogens, and are relatively easy to capture and sample, thus can be considered an ideal model for eco-immunology and diseases ecology.
Recently bats became the focus for human-oriented approaches in infectious disease research as important reservoirs for various emerging viruses. However, they are susceptible to other, extracellular pathogens such as bacteria and fungi. Our work on bat immunology aims to describe and understand the immunological base of these observed differences in susceptibility, to delineate factors explaining the species-specific differences in chiropteran immune phenotype, to understand the effect of different anthropogenic activities (e.g. habitat destruction, pollution) on their health status and its consequences on reservoir competence. We are specifically interested how species adapted immunologically to hibernation (with Depts. Evolutionary Ecology, Evolutionary Genetics and Reproduction Biology), migration (with Dept. Evolutionary Ecology) and reproduction. A major effort of all our projects is to continuously improve the immunological toolkit available for wildlife species, focusing on species-non-specific assays.
Besides bats, we collaborate on similar questions both internally and externally on various avian and mammalian species too.
